LV4924VH
Overview
The LV4924VH is a 2-channel full-bridge driver for digital power amplifiers. It requires a PWM modulator IC in the
previous stage. This IC is a power cell that takes in PWM signals as an input and is used to form a digital amplifier
system for TVs, amusement equipment, and other such systems.
Features
BTL output, class D amplifier system
High-efficiency class D amplifier
Muting function reduces impulse noise at power on / off
Protection circuits incorporated for over-current, thermal, supply voltage drop, output offset detector
Built-in bootstrap diodes
Specification
